MDF, also known as fiberboard, is a man-made board made of wood fiber or other plant fiber, using urea-formaldehyde resin or other suitable adhesive. MDF is a kind of plate that is often used in building decoration. It is also a building material that can't be separated from building decoration. What are the advantages and disadvantages of high-density board ? Let's take a look at the related content of the home of the decoration home network. Let's go!
MDF, also known as fiberboard, is a man-made board made of wood fiber or other plant fiber, using urea-formaldehyde resin or other suitable adhesive. According to their density, they are divided into high density board, medium density board and low density board. Due to its soft and impact resistance, MDF is also easy to reprocess. It is a good material for making furniture in foreign countries. However, because the national standards for high density boards are several times lower than international standards, the quality of MDF in China is used. Still needs to be improved.
The main advantage: MDF is easy to finish. All kinds of paints and paints can be evenly coated on the MDF, which is the preferred substrate for paint effects. The MDF is also a beautiful decorative plate. Various veneer, adhesive film, veneer, light metal sheet, melamine board and other materials can be glued on the surface of the MDF. The hard MDF is punched, drilled, and made into a sound absorbing panel, which is used in the decoration of buildings. Excellent physical properties, uniform material, no dehydration problems.
The main disadvantage: the biggest disadvantage of the MDF is that it is not moisture-proof, and it will swell when it sees water. When using MDF as a skirting board, door panel, window sill, you should pay attention to the six sides of the paint, so that it will not be deformed. The density board has a large water expansion rate and large deformation, and the load-bearing deformation is longer than that of the homogeneous solid wood particle board. Although the moisture resistance of the MDF is poor, the surface of the MDF is smooth and flat, the material is fine, the performance is stable, the edge is firm, and the shape is easy to avoid, causing problems such as decay and insects. It is superior to particleboard in terms of bending strength and impact strength, and the surface of the board is excellent in decoration, which is superior to the appearance of solid wood furniture. The density of the MDF is poor, and the density of the fiber is very small, so that the MDF holding force is much worse than the solid wood board and the particle board.
The surface of the MDF is smooth and flat, the material is fine, the performance is stable, the edge is firm, and the surface of the board is well decorated. However, the density of the MDF is poor, and in contrast, the nail holding force of the MDF is worse than that of the particle board. If the screw is loose after the screw is tightened, it is difficult to fix because the strength of the MDF is not high.

Shelf lighting is a lighting solution specifically designed for commercial and retail environments. Its goal is to highlight and display the goods on the shelves by providing appropriate lighting to attract customer's attention and increase sales.
The classification and layout of shelf lighting can be selected according to different needs and scenarios. LED lamps are the most commonly used shelf lighting technology and are favored for their high efficiency, long life, and dimmable characteristics. Overhead lights and strip lights are common installation locations and can be selected according to the needs of the appropriate way to provide overall or local lighting.
In terms of lighting layout, uniform lighting, and directional lighting are common choices. Uniform lighting ensures consistent lighting intensity for merchandise by providing a balanced distribution of light across the entire shelf. Directional lighting uses lamps such as spotlights or downlights to focus light on specific goods or display areas to highlight their characteristics.
Lighting control is also an important consideration. The dimmable lighting system can adjust the lighting brightness as needed to adapt to different environments and product display needs. Smart lighting systems automatically adjust lighting intensity and color through factors such as sensors, timers, or external conditions, providing greater flexibility and energy efficiency.
Through the appropriate shelf lighting program, businesses can create a pleasant shopping environment, highlight product characteristics, attract customers' attention, and improve sales performance. Shelf lighting plays an important role in modern retail, providing businesses with a means to promote products effectively.
